On 09 March, the thermal capacity of Unit 1 was first raised to 35% of its nominal value, and then its 3000 rpm turbine was successfully put into rotation. The unit was then synchronized to the national grid and its power was increased to minimum electric power of 240 MW. The unit continued producing this power for 4 hours.

Unit 1 at the Leningrad II NPP is the second VVER-1200 reactor connected to the grid. Novovoronezh 6 was commissioned in 2016. The Leningrad NPP will have eight units in total. Four existing RMBK-1000 units, and four new VVER-1200 units. With Leningrad II-1 unit, two NPP units have already been commissioned this year in Russia. Rostov 4 (with VVER 1000 reactor) was connected to the grid on 1 February.
